		<h2>Code Example</h2>


		<code>
		const length = 12, width = 8;

		const shape = new THREE.Shape();
		shape.moveTo( 0,0 );
		shape.lineTo( 0, width );
		shape.lineTo( length, width );
		shape.lineTo( length, 0 );
		shape.lineTo( 0, 0 );

		const extrudeSettings = {
			steps: 2,
			depth: 16,
			bevelEnabled: true,
			bevelThickness: 1,
			bevelSize: 1,
			bevelOffset: 0,
			bevelSegments: 1
		};

		const geometry = new THREE.ExtrudeGeometry( shape, extrudeSettings );
		const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
		const mesh = new THREE.Mesh( geometry, material ) ;
		scene.add( mesh );

		<h2>Constructor</h2>


		<h3>[name]([param:Array shapes], [param:Object options])</h3>
		<p>
		shapes — Shape or an array of shapes. <br />
		options — Object that can contain the following parameters.

			<ul>
				<li>curveSegments — int. Number of points on the curves. Default is 12.</li>
				<li>steps — int. Number of points used for subdividing segments along the depth of the extruded spline. Default is 1.</li>
				<li>depth — float. Depth to extrude the shape. Default is 1.</li>
				<li>bevelEnabled — bool. Apply beveling to the shape. Default is true.</li>
				<li>bevelThickness — float. How deep into the original shape the bevel goes. Default is 0.2.</li>
				<li>bevelSize — float. Distance from the shape outline that the bevel extends. Default is bevelThickness - 0.1.</li>
				<li>bevelOffset — float. Distance from the shape outline that the bevel starts. Default is 0.</li>
				<li>bevelSegments — int. Number of bevel layers. Default is 3.</li>
				<li>extrudePath — THREE.Curve. A 3D spline path along which the shape should be extruded. Bevels not supported for path extrusion.</li>
				<li>UVGenerator —  Object. object that provides UV generator functions</li>
			</ul>

		</p>
		<p>
			This object extrudes a 2D shape to a 3D geometry.
		</p>

		<p>
			When creating a Mesh with this geometry, if you'd like to have a separate material used for its face
			and its extruded sides, you can use an array of materials. The first material will be
			applied to the face; the second material will be applied to the sides.
		</p>

		<h2>Properties</h2>
		<p>See the base [page:BufferGeometry] class for common properties.</p>

		<h3>[property:Object parameters]</h3>
		<p>
		An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
		</p>
